Non-verbal communication provides important additional information beyond what is said verbally. Only 7% of overall human communication comes from words, while 38% is derived from vocal elements like tone and pitch, and 55% from facial expressions and body language. The process of communication involves a sender encoding a message, transmitting it, and a receiver perceiving, decoding, and understanding it. Non-verbal cues like body movements, use of personal space, touch, voice, environment, artifacts, and physical characteristics, whether intentional or not, convey additional meaning that can clarify, contradict, or outweigh what is spoken. Being aware of non-verbal aspects is key to fully understanding communication exchanges.
